Lady Gaga might be a huge superstar but she wasn't a diva when she appeared on Strictly Come Dancing last night.

The quirky singer, who took to the stage with jazz legend Tony Bennett, made the effort to go into the make-up room where the celebrities and professionals were getting ready for the show and chat to them.

Dancer Karen Hauer, who is partnered with former TOWIE star Mark Wright on the BBC show, told Mirror Celeb: "Gaga popped into the make-up room and started talking to everybody - she was really friendly and lovely.

"She had a great energy and was wishing everybody, 'Good luck'. We would have loved a selfie but it was pretty tight on security and we were very busy.

"She gave a hug to a couple of people and started talking to all of us. She was saying that she's a performer as well and she loves dancing and felt we were all in the same boat one way or another.

"Tony Bennett married one of the teachers in my school so it was nice to see him performing once again. I felt I had a close connection."

Gaga, 28, looked stunning for her first UK TV performance with Tony, dressed in a silver slinky dress and her huge brunette curly wig, which she kept on when the cameras stopped rolling.

The global star performed two songs , Anything Goes and It Don't Mean a Thing (If It Ain't Got That Swing), with US crooner Tony, 88, - and fans on Twitter praised her performance.

She re-tweeted one comment which read: "Ummm, why did I not know how AMAZING of a singer Lady Gaga is?! That Strictly performance with Tony Bennett had me tearing up, so beautiful!"

Meanwhile, Karen and Mark were stunned to find themselves in the bottom two last night with antiques expert Tim Wonnacott , who was eventually booted off the show after the dance-off.

Karen said: "When that red light goes on, you feel like you're going to throw up. It's like a nightmare.

"Mark kept on telling me he thought he was dreaming. He was like, 'Is this real? Are we in the bottom two?' I was like, 'Yes, we have to dance again'. But I was really proud of him, he went up there and did it all again."

She admits he gets quite emotional when he sees his family in the audience, especially his grandparents and gorgeous fiancée Michelle Keegan.

Ballroom dancer Karen said: "He gets very teary-eyed when he sees his family - he wants to make them proud but he kept it together.

"When we're under pressure we also put in a lot of hours and get working. It's getting a bit intense now."
